Consistent non-exposure of inherited annotations in AnnotationMetadata

[jhoeller]

Historically, StandardAnnotationMetadata operates against Class.getAnnotations(), potentially seeing inherited annotations as well. This is inconsistent within the AnnotationMetadata abstraction since its ASM implementation operates against locally declared annotations only.

Let's make this consistent in 5.2 since inherited annotations aren't relevant for our component and configuration class introspection purposes, and in particular should be consistently ignored across Class-declared and component-scanned beans.
